I don't think I can fix it w/out damaging any of the the threads. I know of some other ORD folks already who have swapped in flex couplers. I think I will procure some myself now..

Sometimes when using set screws on threaded rod, the rod can tip a little in the coupler. Try rotating the coupler a little and resetting the rod. It may or may not help. Also make sure the motor and threaded rod are not touching too.
The rods came from McMaster, I just cut them to length. They don't have many length options for metric threaded rods.

If you read the instructions and use a piece of soft hose like you're supposed to they work far, far better than you'd expect. It's a very simple print that should still function as intended even with lots of z wobble.
